• Westinghouse iGen5000 runs 18 hours at 25% and 15 hours at 50%.
• WEN 56380i is rated 8.5 hours at 50% load.
• Westinghouse iGen5000 is quieter at 52 dB vs WEN at 57 dB.
• Both are gasoline inverter generators suitable for sensitive electronics.

Best use cases

Choose the WEN 56380i if you want an inverter generator for moderate loads and you do not need marathon runtimes. With 3400 running watts and 3800 starting watts, it is a practical fit for basics like a refrigerator plus some lights, device charging, and a fan, or for tailgating and occasional camping where you can refuel as needed. At 99.2 lb, it is slightly lighter than the Westinghouse, which matters if you are lifting it in and out of a truck or storage more often than rolling it around. The tradeoff is shorter stated runtime at 8.5 hours at 50%, and a higher noise rating at 57 dB, so it is less ideal for all-night use close to people.

Choose the Westinghouse iGen5000 if your priority is longer run time, quieter operation, and more starting power for motor-driven appliances. The jump to 5000 starting watts can help with tougher starts (for example, a larger fridge, freezer, sump pump, or power tools that surge), even though the running output is only moderately higher at 3900 watts. Its 18 hours at 25% and 15 hours at 50% are strong for RV weekends, multi-day outages, or anyone who wants fewer refueling trips. It is also quieter on paper at 52 dB, which tends to feel meaningfully calmer in a campsite or neighborhood. The tradeoff is a bit more weight at 104.7 lb, and you are paying for capacity you may not use if your loads are consistently small.

Verdict & recommendation

If your priority is long, quiet operation with extra starting headroom for appliances that surge, pick the Westinghouse iGen5000. Its 5000 starting watts, 52 dB rating, and up to 15 hours at 50% load make it easier to live with during extended runs.

If your priority is a simpler inverter generator for moderate loads and shorter stints, the WEN 56380i can be a sensible fit, especially if you are comfortable refueling more often and your appliances do not demand big surge power.

In practice, choose based on how long you need to run between refuels and whether your must-run devices have high starting surges.
